Best HVAC Lead Generation Companies (2026, Sourced)

Five mechanics cover the field:

1. Shared per-lead marketplace. One request is sold to several contractors — Angi/HomeAdvisor, Porch and Bark. Angi's own investor definition is the tell: "a single Service Request can result in multiple Leads."
2. Shared marketplace with a published cap. Same model, ceiling committed: Thumbtack publishes "no more than five pros from search results per project within four hours"; Networx publishes "up to 4 contractors in total" per Pay Per Lead.
3. Exclusive pay-per-call. One valid call goes to one contractor: "All of our HVAC leads are sent exclusively to one contractor" at 33 Mile Radius, and the same structure at Service Direct and ResultCalls.
4. Credit-based pay-to-contact. You see leads free and spend credits to reply. Bark publishes "$2.35 per credit" but never credits-per-lead, so no per-lead dollar figure exists to compare.
5. First-party lead buying through Google. Local Services Ads bill per valid lead against a monthly budget maximum. Google publishes the mechanic — "you pay for valid leads" — and no price.

One mechanic is where budgets break. A spend target is not a spending cap: HomeAdvisor calls it an "estimated 28-day period dollar amount", charges Instant Booking and Job Opportunity leads outside it, and concludes "It is possible to exceed your spend target."

Marketplace supply is under pressure: Angi reported Q2 2026 revenue of $248.0 million, down (11)% year over year.

Every cell was read off the linked page on 17 August 2026; prices move.

Eleven companies, seven published prices between four of them, and seven rails where a number would sit. Networx's $14–$100 is an all-trades range rather than an HVAC one, and Bark's $2.35 is a credit price, not a lead price — it publishes no credits-per-lead figure, so none can be calculated.

1. Service Direct — best for a contractor who wants a price before a phone call. Service Direct alone publishes an HVAC-specific per-lead range on its own pricing page: Air Conditioning $65–$325 and Heating $65–$325, with "No Set-Up Fees" and no term contract.

2. 99 Calls — best for a small shop that wants one flat number. 99 Calls labels $54.99 Organic SEO · per lead a flat rate and puts it in its title tag. The condition, printed further down: "Organic HVAC leads are just $54.99 each with the Growth Package or free with Growth Pro." The site those leads arrive through is priced separately — "Have 99 Calls build and host a site for your business for just $99 per month" — so ask who holds the domain.

3. Networx — best documented shared-lead economics. Networx publishes a prepaid range of $14 to $100 per lead and its own cap of up to 4 contractors per Pay Per Lead. Read the auto-renewal clause first: when credits run low, "the account automatically renews your lead balance and charges your card accordingly."

4. 33 Mile Radius — best published definition of a billable lead. 33 Mile Radius publishes no dollar figure, only that "Each valid lead is a low flat-rate" billed weekly — but it publishes the sharpest test of valid: homeowner or decision-maker, requesting an HVAC service, inside your agreed service area. Fail any one and "it is not billable." Onboarding opens with "A 15 minute call to secure your service area," so ask whether yours is taken.

5. ResultCalls — exclusive pay-per-call with a published starting rate. ResultCalls advertises exclusive HVAC calls at "Starting $79.85 Per Call" with "No Long Term Contracts," then says on the same page that rates "start as low as $24.85 per call" — two entry prices on one page.

6. Thumbtack — best competition cap, weakest exclusivity. Thumbtack lets you set lead prices against a weekly budget and publishes a real ceiling: "no more than five pros from search results per project within four hours" of the customer's first contact. It is blunt about the limit: "we can't guarantee that customers will answer when you call."

7. Google Local Services Ads — best for buying leads without a middleman. Google charges per valid lead against a monthly budget and publishes no price. Two 2025 changes matter. Google announced on 20 August 2025 that from October "Google Verified will replace other LSA badges and programs, like Google Guaranteed, Google Screened, License Verified by Google and the Money Back Guarantee" — the consumer money-back promise is inside that list. Separately, disputes became automated credits that no longer cover "job type not serviced" or "geo not serviced".

8. Angi / HomeAdvisor (Angi Leads) — biggest volume, least published. Angi's pro pages publish no per-lead price, no membership fee and no pros-per-lead number. The regulatory record is public: an FTC March 2022 complaint over lead-quality claims, then a consent order requiring payment of up to $7.2 million, and Vermont's Attorney General announcing in October 2025 that Angi would pay the State $100,000 and stop using "Angi Certified Pro."

9. Modernize — for install-heavy shops willing to be account-managed. Modernize publishes an article titled "How Much Do Modernize Leads Cost?" that declines to answer: "The true cost per lead depends." Sharing, credits and contract length are unpublished too, so every term is negotiated blind.

10. Porch — read the credit policy before the pitch. Porch publishes no price and states the refund reality in one line: "we do not process refunds to your credit card." Automatic credits for unresponsive homeowners sit behind Vetted Pro status.

11. Bark — cheapest to test, tightest expiry. Bark charges credits only when you reply, at $2.35 per credit. Credits bought from 1 November 2025 expire after 3 months, down from 12. Credits-per-lead is never published, so no HVAC cost per lead can be calculated from its pages.

One entry most 2026 roundups still get wrong: CraftJack no longer runs its own site. Fetched on 17 August 2026, craftjack.com resolved to signup.angi.com/pro, titled "Get Leads, Win Jobs, Grow Your Business | Angi Pro" — the same supplier as row 8.

The only market-level HVAC averages any vendor publishes come from Service Direct, and they are three years old: "The average CPL of billable HVAC calls in the United States during the first three months of 2023 was about $112", with Texas at $150, the Austin metropolitan area at $234 and Dallas at $143. Treat that as a Q1-2023 snapshot from an interested party, not today's price. The durable lesson is how far the number moves inside one country: $143 in Dallas against $234 in Austin, two markets in the same state measured in the same quarter.

Close rates are where this market goes quiet. No vendor audited here publishes one with a methodology. What exists instead:

That last row is why close-rate promises deserve documentary scepticism. Samuel Levine, Director of the FTC's Bureau of Consumer Protection, said of the order: "Today's order requires HomeAdvisor to refund home service providers millions of dollars and stop misleading them about the quality of its leads." The complaint also alleged many leads were "actually purchased from affiliates and did not come from HomeAdvisor's website" — worth asking every vendor.

Cost per lead is also the wrong denominator. A $65 lead shared with three competitors and a $325 exclusive call can produce identical costs per booked job, and only one ties up your dispatcher. Take a quarter's invoices per vendor, count the jobs those leads booked, and rank on that quotient instead.

Only two vendors publish how many contractors a shared lead goes to: Thumbtack five pros within four hours of the customer's first contact, and Networx up to four in total. Angi's pro contract says only that "We limit the number of Service Professionals that are matched to a customer" — no figure — and that "HomeAdvisor is free to contract with other Service Professionals as this is not an exclusive contract." Bark, Porch and Modernize publish no cap at all.

The credit rules matter more than the price, and every shared marketplace audited here excludes the same situation — losing the job:

• HomeAdvisor lists "You did not win the job" among situations "accounted for in our lead pricing and therefore not eligible for lead credits," alongside "Consumer is just 'shopping'."
• Porch lists "You didn't win the job." and "The customer is just shopping for prices" as not eligible.
• Thumbtack puts the question in its own refund policy — "The customer hired a different pro. Can I get a refund?" — and answers it: "We know it can be frustrating not getting hired, but we don't provide refunds in these situations."

Money that does come back comes back as spending power inside the platform. Porch writes "we do not process refunds to your credit card"; HomeAdvisor issues store credits; Thumbtack states "By default, your refund will be sent to your Thumbtack account balance"; Bark returns credits "Within 14 days of the lead purchase" and adds that "All returns are issued at our discretion."

Raise one documentation conflict with any Angi Leads rep. Two live pages from the same company disagree on how long credits last: the Angi Leads Pro guidelines say "Credits will expire, if not used, six months after the date the Credit was issued", while the Service Professional Terms — last updated 1 October 2018 by the page's own admission — say "eighteen months". Both were live on 17 August 2026.

Five signals that the bridge has done its job:

1. Your published-price vendors are your cheapest, and they've plateaued. Once they stop improving your cost per booked job, more spend buys volume, not efficiency.
2. You are paying for the same homeowner twice. A shared lead you also reached through your own website or Google Business Profile is traffic you rented after earning.
3. Your attribution is guesswork. Scorpion's 2026 State of Home Services Marketing Report — 2,000 US homeowners and 944 home services operators surveyed late 2025 via Dynata — found 67% of business leaders cannot connect marketing spend directly to revenue, while 78% use two or more marketing vendors. Scorpion sells attribution software; that is a vendor survey.
4. Your marketing spend is below the level that correlates with profit. ACCA's Contractor of the Future Study of more than 1,000 HVACR contractors reports that "The average contractor spends 6% of annual revenue on marketing and advertising. Contractors who invest at least 12% see their net profits jump from 5% to 9%." That is a correlation in a survey, not a promised return — but if all of your 6% is per-lead fees, you own nothing.
5. Your lead source is shrinking. Angi's own Q2 2026 filing reports Average Monthly Active Pros down (17)% year over year and Average Monthly Churn of (6.0)%.

The owned alternative is slower: a website that converts, Google Business Profile and map-pack groundwork, reviews collected legally, search visibility, and visibility inside AI-generated answers. Google Search Central settles the guarantee question: "No one can guarantee a #1 ranking on Google." Any agency promising a ranking, a lead count, or a slot in ChatGPT's answers is selling what regulators examine.

Keep the bridge while you build the asset, put the bridge on a budget with an end date, and measure both in cost per booked job. Our owned-pipeline programme audits where your jobs come from today, ships the tracking and booking floor first, then builds the surfaces you keep — search work that keeps producing after the invoice stops, priced against what owned search actually costs to run.

One measured example of what the owned side looks like, published anonymised because that client has not yet confirmed permission to be named: a Winston-Salem HVAC and refrigeration contractor on our SEO engagement is at organic clicks +234.4% and top-10 ranking keywords +426.2% in Google Search Console, measured to 14 August 2026 since engagement start. Two qualifications belong in the same breath. First, the growth has plateaued — clicks peaked around 24 July 2026 at 2,486 for the month and stood at 1,886 on 14 August — and what is capping the account now is technical and measured: LCP 4,260ms against Google's 2,500ms "good" threshold, and 411 unindexed URLs against 268 indexed. Second, clicks are not booked jobs. That figure describes demand arriving at an asset the contractor owns; it is not a cost-per-booked-job comparison against purchased leads, and we will not present it as one.

Our own side is priced in public so the arithmetic above is one you can run before any call: $2,500/month for the SEO retainer, with the AI-search work included rather than billed alongside it, and $2,500 one-time — or $250/month over 12 months, after which you own it — for the website doing the converting. AI services are quoted per shop, because call volume decides that number and a headline price would misstate it.
